To alt whom it may concern:-

Be it known that we, ALAN WOOD, 3d, residing in Lower Merion township, and HARRY A. LEw1s,residing at Norristown,in the county of Montgomery and State of Pennsylvania, citizens of the United'States, have jointly invented a new and useful Roller Stamping-Matain changeable stamps and which is pressed upon the hot metallic sheet, bar, or the like as it passes on the roller-table or issues from the rolling-mill and which is slidablelaterally,

so to be capable of being operatively arranged at various points across the table or mill.

Objects of our improvements are, first, to ide simple, reliable, and comparatively inexpensive means for marking or' stamping sheets, bars, or the like of any metal while hot and capable of being used in connection with.

the operation of a rolling-mill or a roller-table;

second, to afford means for marking orstamp ing sheets, bars, or the like of any thickness as they issue from any part of the rolls in finishing or are being conveyed. upon the roller-= table along any line between the two edges or l sides thereof; third, to provide a means for bars, orthelikeof any metal; fourth, to stamp changing the stamps in order to stamp with distinguishing marks different kinds, qualities, heats, lots, shapes, or s1zes of sheets,

the same along a straight line parallel with the edge thereof throughout their entire lengths at frequent and regular intervalsand before shearing in order that each of the sheared pieces shall be impressed with the dis tinguishing stamps or marks.

The nature, characterlstic features, and

scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which Figure 1 is a side elevational view of a machine embodying features of the invention,

. showing the same in application to a rollingmill and roller-tables.

Fig. 2 is a top view of the hydraulic cylinder, chain, and operatingvalve shown in Fig l. Figs. 3 and 4 are respectively side and end views of the two parts of a small roller adapted to contain the changeable stamps. Fig. 5 is a perspective view of a stamp. Fig. 6 is a partial top sectional view of the machine without the hydraulic cylinder and chain and showing in part the rolling-mill. Fig. 7 is a perspective view of v of the mills, with their different grooves and the bull-head pass for finishing light material. (Best shown in Fig. 6.) 1" represents the rollers of the roller-tables for handling the product." f represents parts of the fore-plates,and are for guiding ingots into the grooves of the rolls; and F is part of the rolling-mill housinvention may be conveniently attached.

' .Hot metal is or may bedelivered from different points across the described machine of different thicknesses; but the invention is not limited to the parts which have been explained,

lasthey are represented to illustrate a con venientmethod of attaching and operating the mechanism embodying the invention.

, The revoluble shaft A is shown as arranged to turn in a bearing E in the mill-housing F and in a similarbearing in the other mill-housing, Figs. 1 and 6. The sliding lever-arm B slides along the shaft A by means of a mechanism. (Best shown in Fig. 6. Shaft A has two ing to which the mechanism embodying the long grooves or keyways Z0 and 70 from end to end (passing through the housings) directly op- A key ,1; (best made. of-

posite each other. bronze) on the lever-arm B fits into one of the keyways k.

The lever-arm may thus be slid horizontally :along the shaft without turn- 5 ing. 'A small chain or the like, X, (a part Of' which is not shown,) is fastened to the right end of the key 7, runs along inside the keywayk andover the sprocket-wheel-S, which is at tached to the end of shaft A. Thence it runs along inside the other keyway k and around sheave-wheel u, attached to the other end of shaft A, thence along keyway 7e, and is fastened to the left end of key 9. The sprocketwheel S is geared to the handle T, which drives the sprocket-wheel S. The lever-arm B can be slid back and forth over the rollertable and in front of the rolls, so that thehot metal sheets, bars, or the like can be stamped from whichever part of the rolling-mill they issue in finishing. In order to slide the leverarm B easily along shaft A by hand-power, it may be balanced. This may be accomplished either by a counterweight on end of B opposite to the end which carries the part c, as shown, or by swinging the lever-arm B to a vertical position, thus avoiding friction of key 1) in its keyway. On the outer end of the lever-arm B the small roller Q is set upon an axle at right angles to the lever-arm.

To enable the use of changeable stamps, the roller Q is made in two pieces, a body-piece Q and a nut-piece Q, as shown in Figs. 3 and 4:. A conical interrupted triple thread 2. may be used to make the separation of the nut and body of the roller quickly. By fitting them so that the-thread tbottoms just before the nut is up looseness and shaking of the two roller parts against each other are prevented. The thread tshould be left-hand. Fig. 3 shows the recesses for the changeable stamps. These recesses a are located upon the edge of the body of the roller Q, and exposed by the removal of the nut end Q. There is a projecting key or round pinb on one side of each recess. The changeable stamps (shown in Fig. 5) are of a size to fit in the recesses a and have a round keyway, corresponding to the key or round pin 6, to hold them firmly in place. The letter, figure, or device to be stamped may be raised to extend above the surface of the roller about one-eighth of an inch. The recesses a may be made of unequal depth, so that the first and last stamps project about one thirty-second of an inch less beyond the surface of the roller than the middle ones. By this means all the stamps print of nearly equal depth. In Fig. 8 there are shown two sets of recesses of four each on directly opposite sides of the roller. This enables the stamping of the letters or numbers twice for every revolution of the roller Q. Other convenient and similar arrangements readily occur to those skilled in the. art and may be used in lieu of the abovedescribed arrangements for the holding of the interchangeablestamps in the roller.

Fig. 7 shows a convenient retainer for holding the roller Q on its axle. The retainer 0 consists of a nut with a short handle, having an interrupted thread, so that a quarter-turn backward frees the retainer at once. The thread in the retainer should be right-hand, so that the rubbing of the roller Q, in which the thread is left-hand, tends to tighten both. By making the retainer small enough in diameter to enter the counterbore Q, on nut end Q of roller Q and the boss of lever-arm B against which roller Q, rubs too large to enter the operator will be prevented from putting the roller on the wrong way.

In order to keep the stamps cool and preserve their hardness, a small water-pipe \V on the lever-arm B is arranged to throw its jet on the stamps in roller Q. The inner end of W is attached to a flexible rubber hose /i, which connects with the suppl \'pip 'lhe Water-cock c, Fig. 1, in the supply-pipe is connected by a lever and link to the hydraulic operating-valve O, so that the water is turned on automatically when the machine is put in operation.

The lever-arm B is operated by the mechanism best shown in Fig. 1. A wheel O is fastened to shaft A outside the housing F. The cast-iron plate (Jr, in which the end of shaft A revolves in a bearing, is held in position by the round nut H, which screws on the hydraulic cylinder 1, and also by a bracket lowerdown. (Notshown) 'lheblock liishcld firmly in place by being fitted into a notch in the plate G and by being bolted to hydraulic cylinder 1. Connection 1), a chain, is fastened to block K on the right-hand side, as by an adjusting eyebolt, and passes horizontally over sheave-wheel J on end of hydraulic plunger J, thence around sheave-wheel L, which is hung on the left end of block K, thence vertically up and around chain-wheel O, to which it is fastened by the pin N, which prevents the chain from slipping upon wheel A counterweight M is hung upon the end of chain D. The hydraulic plunger J is operated by the cylinder I and is controlled by the hydraulic valve O.

The machine is operated by adjusting the lever-arm B and roller Q, containing the interchangeable stamps, by means of the handle T, so that it is on a line with the part of the rolls from which the sheets, bars, or ingots are to issue in finishing. The operating-valre O is then thrown open, and the ph'luger J, pushing outward on the chain l), causes the wheel-shaft and lever-arm to turn and press the roller Q upon the hot metal as it passes beneath, thus stamping the metal from end to end with the numbers or letters set in the roller Q. On releasing the hydraulic pressure the counterweight M raises the lewr-arm B and returns the plunger J into its cylinder 1. When the plunger J is at the bottom of cylinder, lever-arm B should stand upright. Where the stamps are arranged, as in the accompanying drawings, to print one at a time in succession, it requires about six hundred to one thousand pounds actual pressure to stamp plainly with letters or figures of about three-eighths of an inch in length.

The mechanism above described may be set upon a separate framework over a roller-table, or where no roller-table is used in connection with arolling-mill it may be attached kinds, qualities, heats, lots, shapes, or sizes,

The number and arrangement of the recesses and stamps may be readily altered from that shown in the above drawings, so-as to stamp either crosswis'eor longitudinally or diagonally to the length of the 'sheet, bar, or the like as it passes beneath, and the intervals be-.

tween each set of stamping may be regulated by the size of the roller, it being of course understood that in such. case the number of stamps remain the same, so that the intervals between them will naturally be increased along with the length of the periphery.

While hydraulic power is used in the mechanism described above, any other power may be used for the rotating of the, shaft and sliding lever-arm and for the pressing of the roller with interchangeable stamps upon the hot metal.

. It will be obvious to those skilled in the arts to which the invention relates that modifications may be made in details without departing from the spirit thereof. Hence the invention is not limited further than the prior state of the art may require; but,

Having thus described the nature and objects of our invention, what we claim as new, and desire to-secure by Letters Patent, is-
